Collagen and elastin
The two layers of the dermis are the papillary dermis, which is the upper layer closest to the epidermis and contains blood vessels and sensory receptors, and the reticular dermis, which is the deeper layer made up of dense connective tissue, collagen fibers, and sweat glands.
Proteins and nucleic acids
The dermis is a layer of skin between the epidermis and subcutaneous tissues, and is composed of two layers, the papillary and reticular dermis.
The dermis is the deep layer of the skin - just below the epidermis. The dermis is made up of two types of connective tissue: the superficial layer of the dermis is areolar CT and the deep layer of the dermis is dense irregular CT.
Epidermis and dermis.
No, proteins and lipids (fats) are two different classifications of organic molecular constructs.
proteins and phospholipids
There are two main types of proteins namely; simple proteins and conjugated proteins. Simple proteins only contain amino acids while conjugated proteins contain organic and inorganic groupings in addition to amino acids.
The two organic molecules that always contain nitrogen in their subunits are nucleic acids and proteins. Nucleic acids, such as DNA and RNA, include nitrogenous bases (adenine, thymine, cytosine, guanine, and uracil) that contain nitrogen. Proteins are made up of amino acids, which all contain an amine group (-NH2) that includes nitrogen.
