Proteins
Fibrous proteins
These molecules are the key structural materials of animal tissue and are present in animal hair, nails and muscle.
Fibrous proteins have their lengthy, spiral chains folded to type lengthy, skinny shapes. They’re robust and are typically insoluble in water.
Globular proteins
Globular proteins are molecules concerned within the regulation of life processes. For instance, haemoglobin, and sure hormones like insulin and enzymes are all examples of globular proteins.
They’ve their spiral chains folded intro spherical shapes and are typically soluble in water.
Nonetheless the protein chains are organized, they’re held in these shapes by intermolecular bonding between the facet chains of the amino acids concerned.
Throughout cooking, when the proteins are heated, the molecules turn out to be agitated and transfer round inflicting the intermolecular bonds between molecules to be damaged.
This enables the protein to denature (change form) which modifications the feel of meals. This explains the distinction in construction between a uncooked egg and a fried egg.
