Vitamin A: Structure, Properties, Functions, and Deficiency

Vitamin A structure and functions

Vitamins are the organic compounds occurring in small quantities in different natural foods and necessary for growth and maintenance of good health in human beings and in experimental animals. Basically, vitamins can be divided into two types based on solubility. Vitamins mean Vital Amines They are  Fat-soluble (Vitamin A, D, E, and K)Water-soluble (B-Complex vitamin and Vitamin C) In this …

What are Polysaccharides and How it was Classified?

polysaccharides and its types

Carbohydrates composed of ten or more monosaccharide units are classifieds as polysaccharides, and their molecules are colloidal in size. They may be considered as condensation polymers in which the monosaccharides (or their derivatives such as the amino sugars and uronic acids) are joined by glycosidic linkages. By far the most important naturally occurring polysaccharides are Starch and Cellulose. Another term for the …

VITAMINS : The Micro-Nutrients in Our Body

VITAMINS : The Micro-nutrients in Our Body

The essential Macronutrients are water, proteins, carbohydrates, fats, vitamins, and minerals. In developed countries, vitamin deficiencies result mainly from poverty, food fads, drugs, or alcoholism. Vitamin toxicity (hypervitaminosis) usually results from taking mega doses of Vitamin A, D, B6, or niacin. In general, excess amounts of water-soluble vitamins are excreted via the Kidneys. Vitamins may be fat-soluble (vitamins A, D, …

What are the Classifications of Carbohydrates? Explain with Examples

carbohydrates classification

Today we are discussing the basic concept of Carbohydrates Classification from Biomolecules chapter. Carbohydrates are the organic molecules that are composed of the elements carbon, hydrogen, and oxygen. What is Carbohydrate? These sugars are referred to as saccharides. Carbohydrates are defined as polyhydroxy-aldehydes or polyhydroxy ketones or compounds, which produce them on hydrolysis. They supply energy and serve as structural constituents. Carbohydrates …

Fatty acids are the Building Blocks of Fats and Oils (Short Notes)

fatty acids structure

Do you know fatty acids are the basic unit of which macromolecules? Fats are esters of high molecular weight containing Fatty acids(FA) and Glycerol. What are the building blocks of fats? Glycerol is trihydric alcohol and therefore one two or all the three hydroxyl groups (OH) can react with FA forming mono, di or triglycerides respectively. fatty acids are the basic unit …

What is Zwitter Ion and Isoelectric point

zwitter ion and isoelectric point

Amino acids have at lease two ionizable groups, i.e., -COOH and -NH2+, of which the former dissociates more easily than the latter. at physiological pH (7.3), the carboxyl group exists in ionized form whereas the amino group remains undissociated and thus retains a positive charge. This doubly charged molecule of amino acid containing a negative and a positively charged group …
