Lipids perform important functions in the human body, from storing energy and regulating temperature to forming cell membranes and supporting vital functions in both animal and plant cells. They are a source of metabolic energy for reproduction, movement, and migration. [source] In this article, we will discuss the most important functions of lipids. Functions of … Read more
Lipids are a group of naturally-occurring molecules that are insoluble in water but soluble in organic solvents. Examples of lipids include fats, waxes, sterols, triglycerides, phospholipids, sphingolipids, and glycolipids. Common Examples of Lipids Here are some examples of Lipids : Glycerolipids Glycerolipids are special fats made up of glycerol and fatty acids. Triglycerides is common … Read more
LEARNING OBJECTIVES In this article, author has explained the introduction, structure and functions of RNA. Author has also explained the different types of RNA. RNA is a polymer of ribonucleotides that are held together by 3´ 5´ phosphodiester bonds. It is a nucleic acid that helps in the synthesis of proteins. RNA is involved in … Read more
LEARNING OBJECTIVES In this article, author has explained the introduction, structure and functions of DNA. author has also explained the characteristics of double helix structure of DNA and replication of DNA. Definition DNA is a nucleic acid that is a polymer of nucleotides and is responsible for the transmission of hereditary information from parent to … Read more
LEARNING OBJECTIVES In this article, author has explained the structure of nucleotides, different types of nitrogenous bases and functions of nucleotides. Definition Nucleotides are organic compounds that make up nucleic acids. They are building blocks of DNA. Nucleotides are essential parts of DNA, RNA, and cell function and perform many functions based on their structure. … Read more
LEARNING OBJECTIVES In this article, author has explained the introduction to nucleic acids their structure, biosynthesis and functions. Definition A nucleic acid is a polymer of nucleotides that stores genetic information in the cell. Nucleic acids are also known as polynucleotides. It is a large molecule that is made of many small molecules called nucleotides. … Read more
LEARNING OBJECTIVES In this article, author has explained the causes, process and characteristics of denaturation of proteins. Definition The disorganization of the native structure of proteins is known as denaturation. It involves the breaking of many weak linkages and bonds. Denaturation destroys the secondary, tertiary, and quaternary structures of proteins. It affects the chemical, physical … Read more
LEARNING OBJECTIVES In this article, author has explained the tertiary, quaternary structure of proteins and their characteristics. Tertiary structure of proteins The three dimensional structure of proteins is known as tertiary structure of protein. The tertiary structure is formed due to interaction between R groups of amino acid that make up proteins. The protein folds … Read more
LEARNING OBJECTIVES In this article, author has explained the secondary structure; alpha helix and beta pleated sheet structure and their properties. The conformation of the polypeptide chain formed by twisting and folding is known as the secondary structure of proteins. The amino acids are close to each other in the secondary structure. There are two … Read more
LEARNING OBJECTIVES In this article, author has explained the primary structure of proteins, peptide bond and determination of primary structure. The linear sequence of amino acids forming the polypeptides is known as the primary structure of proteins. The polypeptide containing more than 50 amino acids is termed “protein”. Each protein has a unique sequence of … Read more
