Relative importance of each use in plants and animals

Both proteins and carbohydrates are of vital importance to the living world.

Proteins are essential to maintaining the structure and function of all life. The word itself is derived from the Greek word “protos” meaning primary. Proteins are vital for the growth, repair, and maintenance of muscles, blood, internal organs, skin, hair, and nails. After long hard workouts, protein is essential to rebuild worn out tissue, and rebuild muscle.

Proteins are polymers and work by being broken down into smaller components named amino acids, and then rebuild again where and when they are needed. These amino acids join together as chains which can be twisted and folded depending on the molecular structure. There are twenty different types of amino acids found in proteins which can be arranged in any order in chains last

Fibrous proteins have different properties so therefore have different uses of much importance. Their peptide chains are intertwined in long threads. As they are not easily denatured, like globular proteins, they have a structural function by giving support to tissues. Such examples are keratin in our hair and skin. Most important is collagen. They supply bones with their flexibility and make leather out of the tanning process.

In plants proteins are vital in the cell membranes The Glycoprotein, which exist on the outside, is very important for cell recognition. The intrinsic proteins float around the matrix.

Haemoglobin in red blood cells is one such use, consisting of four polypeptide chains with iron; they are modified by being linked to mineral ions. Other proteins can be linked to carbohydrates to form glycoproteins. Its function is to inhibit the enzyme elestate produced by white blood cells to keep elastic tissue in the lungs intact.
